HYDRAULIC ORE=SIZER.

SPECIFICATION forming part of Letters Patent No. 390,717. dated October9, 1888.

Application tiled February 1, 1888. Serial No. 262,592. (No model.)

To @ZZ whom it may concern.-

Be it known that l, JAMES SYMoNs, a citizen of the United States ofAmerica, residing at Ilse, in the county of Custer and State ofColorado, haveinvented certain new and .useful Improvements in HydraulicOre-Sizers, of whiclrthe 'following is a specification, reference beinghad therein tothe accompanying drawings. lo Myinvention relates toimprovements in oresizers for separating granular substances andminerals of different specific gravity by agilating them in a current ofwater while inclosed in a suitable receptacle; and the objects t of myimprovement are to produce a simple and inexpensive machine of thisclass easily controlled in its operation. I accomplish these objects bythe construction illustrated in the accompanying drawings, in which-Figure l is a plan ofa machine constructed in accordance with myinvention. Fig. 2 is a vertical section ofthe same. Fig. 3 isahorizontal section of the discharge-pipe on line a: :c of Fig. 2,showing a top view of the discharge-regulating valve.

In the drawings, A represents a conical receiver, into which the groundore is conducted in any suitable manner. It has a closed bottom; butperforations a are provided inthe 3o sides thereof for the gradualescape of the Inaterial acted upon, said escape being caused by acurrent of water admitted in a conical funnel, B, surrounding thereceiver A, but having its walls at a suitable distance therefrom "f loallow a current of water to pass between them. For that purpose thereceiver A is retained suspended in the interior of the conical funnel Bby means of radiating braces a2. The lower end of this funnel terminatesin a ver- 4o tical pipe, B, receiving on one side thereof one end of thepipe O, through which water received from a suitable height or underpressure is brought into the apparatus.'

The lower end of the vertical pipe Btis provided with a flange, b2, tothe under side of which is pivoted the gate D upon a bolt, d, passingthrough said flange. This bolt retains one end of the gatcin closecontact with the under side cf said flange, and the opposite 5o end issimilarly retained in contact with the tlange by a clip, d2, riveted tothe top of the gate, and havingits upper flange-resting upon the ange b2of the pipe. The gate is provided with a side projecting handle, d3, tooperate it, and it has an opening, dt, in its side that can be made tomore or less coincide with the opening in the lower end of the pipe B2,through which the ore and clear water are discharged. The upper end ofthe outer funnel,

B, is surrounded by au inclined trough, E, to 6o receive the Iinesandand sli me carried upward by the current of water, and from which it isconducted through the opening ein the side thereof to the slime-tablesfor further treatment.

By this construction the pulp or ore is evenly distributed andpenetrated by the water. The heavy mineral falls to the bottom of thevertical pipe B2, and escapes through the regulable opening d* in thegate; but said opening 7o is entirely closed when the machine is not inoperation. The light or tine ore escapes through the perforations a andis discharged by overflowing upon the trough E.

Having now fully described my invention, I claim- 1. The combination ofa conical receiver having rows of perforations all around the sidesthereof, supports forsaid receiver, aconical funnel surrounding saidreceiver, and a S0 trough surrounding the upper end of the latter on alower level than the top of the receiver, with a pipe, B, in thelowerend of the said funnel and gate therein, and a water-conductingpipe entering the side of said pipe B2 85 above said gate,substautially'as and for the purpose described.

2. The combination of a conical receiver having perforations all aroundits sides, a conical funnel surrounding it, radiating braces 9o unitingsaid receiver and funnel, and a trough surrounding the latter, with awater-conductor, C, and a pipe, BZ, in the lower end of said funnel,substantially as and for the purpose described.

In testimony whereof I affix my signature in presence o f two witnesses.
